exploit in buying nexus icon

hello riot i would like to report on an exploit or a bug concerning the buy on nexus tokens as it seems when u buy the icon of 15 tokens for example its owned , but i f u click the snowdown tokens and immediatly re-click on the nexus tokens u can fast click it it still shows u that u can buy it for a strong 1 sec or so if u click it u can re buy the icon wich will be included in the store loot so u can now abuse the fact of dissmanting it to orange essence over and over again
